CORTIS released "REDRED" on April 20, 2026, as the lead single from their second EP GREENGREEN. The choreography — co-created by the members — has been one of the most-covered K-pop dances of the year. Here is how to learn it.

How to Learn the CORTIS REDRED Dance

Start with the official source material, then move to tutorials that break it down at slower speeds.

1. Watch the official dance practice. CORTIS published a fixed-camera dance practice video on April 27, 2026. This is the reference — full choreography, no cuts, no effects. Watch it a few times before trying to learn anything. Get familiar with the structure and notice which sections repeat.

2. Learn section by section. Do not try to learn the full routine in one pass. Tutorial channels typically break REDRED into four sections of eight-counts. Learn one section, drill it at slow speed until it is clean, then move to the next.

3. Practice at reduced speed. Most people can follow the moves at 0.6x–0.8x but fall apart at full tempo. The song is faster than it sounds, and the transitions between sections are tight. Use slow-practice videos or YouTube's playback speed control to build up gradually.

4. Mirror the tutorial, not the practice video. The official dance practice is not mirrored — the members are facing the camera. Tutorial channels flip the video so you can copy what you see directly. If you are learning by watching the official video, remember to reverse left and right.

Official Dance Practice and Tutorial Videos

These are the main resources for learning the REDRED choreography:

• CORTIS 'REDRED' Dance Practice (Fix ver.) — The official practice from CORTIS's YouTube and Weverse. Full speed, not mirrored. This is the reference choreography.
• Dance Buzz — Count + 0.8x + 0.65x Slow Ver. — English tutorial. Breaks the routine into four counted sections, then runs through the full choreography at 0.8x and 0.65x with music. Good for learning the counts and timing.
• 코르티스 REDRED 안무 배우기 — Mirror Mode — Korean tutorial with detailed verbal explanation of each movement. Covers footwork, hip isolations, and the repeated rotation sections. Mirrored.
• Slow to Full Speed — 0.5x to 1x, Mirrored — No talking. Starts at half speed and gradually ramps to full tempo. Useful once you know the moves and want to drill them up to performance speed.

Common Mistakes and Practice Tips

Based on what the tutorial channels flag:

• Rushing the transitions. The sections connect quickly at full speed. Most people who can do each section on its own fall apart between them. Practice the last two counts of one section into the first two counts of the next — that is where it breaks down.
• Leading with the shoulders instead of the hips. The choreography has rotation sections where the hip initiates the movement and the upper body follows. If you lead with your shoulders it looks stiff. The Korean mirror-mode tutorial covers this in detail.
• Ignoring the dynamics. REDRED has a deliberate contrast between controlled, precise movements in the verse and high-energy bursts in the chorus. Performing everything at the same intensity makes the choreo look flat. Watch the official practice and notice where the members pull back versus where they go full out.
• Skipping the slow practice. Going straight to full speed without drilling at 0.65x is the most common reason people give up. The slow-to-full-speed video exists for this reason.

How Long Does It Take to Learn?

This depends on your dance background. Rough expectations:

• Experienced dancers: A few focused practice sessions to learn the structure, then refinement. The choreography has repeating sections, so once you learn about 60% of the unique moves you have most of the routine.
• Intermediate: A week or so of daily practice, section by section. The chorus is the hardest part and will take the most repetition.
• Beginners: Longer, but the tutorial videos at 0.5x make it approachable. Focus on learning the first section and the chorus — those are the most recognizable parts if you want to film a cover without doing the full routine.

The good news is that REDRED has more repeated sections than most K-pop choreography. Once you learn the core phrases, they come back.

Want to Make a REDRED AI Dance Video?

If learning the choreography is not your goal and you just want a video of yourself in the dance, there is an AI option.

The CORTIS REDRED template on Summrs uses a fan-created dance inspired by the Studio Choom performance. Upload your photos, generate, download the MP4, and post it.

No practice required, but also no substitute for actually learning the dance.

FAQ

What is the official dance practice video? CORTIS published the REDRED Dance Practice (Fix ver.) on April 27, 2026. It is a fixed-camera, full-speed recording of the complete choreography. This is the standard reference for covers and tutorials.

Is the choreography hard? It is considered intermediate to advanced for K-pop choreography. The individual moves are learnable, but the speed and transitions are demanding. The repeating sections help — you do not need to memorize as many unique phrases as some other routines.

Can I learn just part of it? Yes. The first section and the chorus are the most recognizable. Many cover videos film just those parts.

Do I need to be mirrored? If you are learning from the official dance practice, the video is not mirrored — you need to mentally flip left and right. The tutorial channels linked above offer mirrored versions so you can copy directly.

When was REDRED released? April 20, 2026, at 6 PM KST. It is the lead single from CORTIS's second EP, GREENGREEN, which was officially released on May 4, 2026.
